Inventor: TSUDA AKIHIRO
IPC: C21B9/10
Filed: 1993-04-13
Abstract: PURPOSE:To allow highly accurate monitoring of the deterioration of thermal insulation cover by winding an optical fiber cable at an arbitrary interval while fitting tightly to the surface of an iron skin using a fixing frame and then connecting the optical fiber cable, at the opposite ends thereof, with a laser light source and a detector. CONSTITUTION:A temporary stop metal 7 is temporarily welded to the iron skin 2 of an external-combustion hot gas furnace. An optical fiber cable 1 is then laid while stapling with the metal 7. The cable 1 is wound at an interval of 1-3m such that the dome and the coupling pipe are wound densely but the straight drum part is wound coarsely. The fixing base of thermal insulation cover, i.e., an inside fixing frame 4, is then wound around the iron skin 2 thus pressing the cable 1 against the iron skin 2 by means of the metal frame 4. A stud bolt 11 is welded to the metal frame 4 and a thermal insulation member 5, a thermal insulation cover 3, and an outside fixing metal 6 are then fixed sequentially thereon and a nut 12 is tightened. When a laser pulse light is sent into the cable 1, it is scattered variously and the temperature at each light scattering point is determined based on the intensity of Raman backscattering light on the anti-Stokes side.

Title: Ptc device
Inventor: TAKADA MAYUMI
IPC: H01C7/02
Filed: 1990-04-25
Abstract: PURPOSE:To enhance the adhesive strength between a PTC device body and a metal-foil electrode by roughening the surfaces of the metal-foil electrodes which touche the PTC device body by an alternating ion etching method. CONSTITUTION:In a device in which metal-foil electrodes are provided to a PTC(Positive Temperature Coefficient) device body made of a conductive polymer compound, the surfaces of the metal-foil electrode 2 of rolled metal foil, that touche a PTC device body 1, are roughened by an alternating ion etching method (ACE method). Since the roughness of the joining surfaces of the metal- foil electrodes roughened by the ACE method is uniform over the entire surfaces, they can be uniformly joined with all portions of the PTC device body and the joining strength is high. Also, since the ACE method is used, no oxide film is formed on the roughened surfaces even when the metal foil is of copper. As a result, it is possible to obtain a PTC device with a strong adhesion between the metal-foil electrodes and the PTC device body and with a stable resistance value.

Title: Method for controlling paper feeder
Inventor: MORI HIROSHI
IPC: B65H1/24
Filed: 1990-04-25
Abstract: PURPOSE:To easily prevent double feed by providing a constitution such that a bottom plate is lifted after leading recording paper passes a feed roller. CONSTITUTION:A following recording paper sheet P is not brought into press contact with a pickup roller 3 before a leasing recording paper sheet P passes through a feed roller 4. Consequently, possibility of a double feed is eliminated even when the feed roller 4 and the pickup roller 3 are always held in a coupled condition. Extension of cycle time due to a timing delay of lifting a bottom plate is recovered by increasing a linear speed V' of the feed roller 4 or advancing lift time (t) of the bottom plate according to the equation. In this way, printing efficiency is prevented from deteriorating due to extending a paper feed interval. Herein L represents a distance from the feed roller 4 to a paired resist rollers 6, and V is linear speed thereof.

Title: Method for recognition of pattern on surface of semiconductor substrate
Inventor: KOYAMA HIROSHI
IPC: H01L21/30
Filed: 1984-05-28
Abstract: PURPOSE:To enable to perform a precise recognition of pattern on the completely flattened surface of a semiconductor element substrate by a method wherein an electron beam channelling phenomenon is properly utilized. CONSTITUTION:An electron beam channelling phenomenon is generated by having the effect of the synchronism of crystal on the interaction between an electron beam and a solid body, and the intensity of emitted reflection electrons 10 indicates a characteristic distribution such as false Kikuchi pattern and the like when the angle of the incident electron beam 9 against a crystal lattice is changed. As the direction of elastically scattered reflected electrons is brought into the state of random and nothing is contributed for channelling, the electron beam channelling pattern reflects only the information on the region in the depth of approximately 50nm from the surface. Also, this state depends greatly on crystallizability as a matter of course, no channelling pattern appears on the part of amorphous substance such as silicon oxide or the amorphous silicon part whereon ions are implanted. Accordingly, the insulating layer 7 such as an oxide film isolated part, an ion-implanted region 8, a high density impurity doping part and the like can be provided in the accuracy of submicron even on the element substrate, the surface of which is completely flattened.
